TELEG RAPHIC INSTRUMENT.

SPECIFICATION forming part of Letters Patent N 0. 670,980, dated April 2,1901. Application filed September 4, 1900. Serial No. 29,014. (No model.)

To ctZZ whom it may concern:

Be it known that I, AMBROSE S. BISSELL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Telegraphic Instruments, of which the following is a full and complete specification, such as will enable those skilled'in the art to which it appertains to make and use the same.

This invention relates to telegraphic instruments; and one object thereof is to provide an improved instrument of this class which employs a tape which in the act of receiving the message is perforated, so as to form the Morse telegraphic characters so that they may be read by sight, a further object being to provide an instrument of this class which will operate as a receiver and also as a transmit ter or repeater of a message once received thereby, and a further object being to provide an instrument of the class described which is particularly designed for use as an instructor or teacher of telegraphy, but which may also be used for. the purposes of a 'receiver in ordinary business.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same reference characters in each of the views, and in which Figurel is a'plan View of myimproved telegraphic instrument; Fig. 2, a partial central vertical longitudinal section on the line 2 2 of Fig. 1; Fig. 3, a section through adetail of the construction on the same line as Fig. 2; Fig. 4:, a plan view of a part of the construction shown in Fig. 3, and Fig. 5 a side view of another detail of the construction.

In the practice of my invention I provide a plate orsupport 5, which isprovided adjacent to one end with a rectangular opening 6 and at the left-hand end thereof and near the opening 6 with two rollers 7 and 8, between which the tape 9, employed in my improved telegraphic instrumen t,is passed, said rollers being designed to feed the tape, regularly and automatically during the operation of the instrument.

The rollerS is provided at one end with a gear-wheel 10, which in practice operates in connection with a clockwork mechanism mounted beneath and connected with the plate or support 5, but which forms no part of this invention, and is therefore not shown and described.

Extending,longitudinally of the rectangular opening 6 are two rods 11, on which is mounted aslidable frame 12, and passing centrally through this frame and midway between the rods 11 is a screw-shaft 13, having bearings at 14, and one end of which is provided with a beveled gear 15, which operates in connection with a corresponding gear 16 on a shaft 17, mounted transversely of the plate or support 5 and provided at one end with a knob or head. 18, by which it is operated, and by turning the shaft 17 by means of the knob or head 18 the screw-shaft 13 is also turned for the purpose of adjusting the frame 12 longitudinally of the plate or support 5.

The frame 12 is rectangular and oblong in form and is so arranged that the greatest length thereof extends transversely of the plate or support 5, and mounted therein, longitudinally thereof, are two rods 19, on which is mounted a supplemental frame or block 20, and a screw-shaft 21 is passed centrally through the supplemental frame or block transversely of the plate or support 5, and by means-of this shaft the supplemental frame or block 20 may be adjusted transversely of said plate or support and transversely of the line of adjustment of the frame 12.

The supplemental frame or block 20 is provided centrally with a transverse space oropening 22, which extends transversely of the plate or support 5, and mounted therein is an adjustable block or device 23, provided at one side with a tongue 24:, which fits in a corresponding groove formed in one side of the frame or block 20 and'at the other side with an arm 25, mounted on a screw-shaft 26, passing longitudinally through a space or chamber 27 parallel with and communicating with the space or opening 22, and the block 23 may be adjusted in the space or opening 22 by means of the shaft 26, and said block is provided, centrally of the top thereof, with a slight depression 28.

Placed upon the supplemental frame or tion by four corner-posts 30, each of which is screw-threaded at its upper end and provided with a nut 31, and placed on each of these posts, below the nut thereon, is a spring 32, and these springs serve to hold the plate 29 in position. The plate 29, which, together with the supplemental frame or block 20, is shown in Fig. 4, is provided with a central slot 33 and a supplemental parallel slot 34 at one side thereof, and these slots extend in said plate transversely of the plate or support 5 and of the rectangular opening 6 formed therein, and the centralslot 33 is directly over the block 23 and over the depression 28, formed in the top thereof.

, Mounted over the right-hand end of the plate or support 5 and preferably midway between the opening 6 and said end of said plate or support is a yoke-shaped support 35, secured to or mounted on a plate 36, and in front of said support are placed electromagnets 37, and pivoted in said support is an armature-arm 38, said pivotal connection being made at 39, and said arm is provided with an armature 40, which operates inconnection with said magnets and is also extended longitudinally of the plate or support 5 over the opening 6 and into an upright bracket 41, provided with two transverse members 42 and 43, and the lower transverse member 43 is provided with a vertically-arranged screW- 44 and the upper transverse member 42 with a similarly-arranged screw 45, provided with a set-nut 46, and the lower end of which at 47 is composed of insulating material and is adapted to bear on the end of the armature-arm 38, as is also the upper end of the screw 44. I

The armature-arm 38 is provided at its right-hand end with a spiral spring-48, which is connected with a screw 49, passed through an arm 50* on the yoke-shaped support- 35, and said screw is provided with a set-nut 51. The armature-arm is also provided midway between the electromagnets 37 and the upright bracket or support: 41 with a vertically-arranged screw 52, with the lower end of which is connected in any desired manner an asbestos block ormember 53, and said screw serves as a connection for two supports 54 and 55, each of which is angular in form and composedof two arms, one arm being longer than the other, and the screw 52 is passed through the shorterarm of each of said supports, and the longer arms thereof converge toward the lower end of the asbestos block or member 53, and the support is insulated from the armature-arm and also from the screw 52, while the support 54 is in electrical connection with said screw and arm.

The lower end of the asbestos block or-member 53 is formed as shown in Fig. 5, being tapered and pointed, as shown at 56, and connected with the lower converging ends of the supports 54 and 55, as shown at 57, is a platinum wire 58, said wire being passed below and formed into a loop around the pointed end of the asbestos block or member 53.

The right-hand end of the plate or support 5 is preferably provided with a central chamber 59, which opens outwardly and also into the rectangular opening 6, and through this chamber the tape 9 in practice is passed, and directly over said end of the plate or support 5 are placed two binding-posts and 61, and two similar binding-posts 62 and 63 are placed on the adjacent end of the plate I also provide a battery 64, provided with circuit-wires 65 and 66, which are respectively connected with the binding-posts 60 and 61, and said binding-posts are connected with the magnets 37 by'circuit-wires 67 and 68, and said magnets are connected by a wire 69, and placed in the circuit thus formed is a telegraphic key 70. I also preferably employ a supplemental circuit consisting of a battery 71, connected with the binding-posts 62 and 63 by wires 72- and 73, and the binding-post 62 is insulated, as shown at 74 in Fig. 2, and is connected with the screw 44 by a wire 75. Another circuit is also employed, comprising a battery 76, having wires 77 and 78, and the wire 77 is connected with an arm 79, formed on the upper horizontal member of the support 55, while the wire '78 is connected with the end of the armature-arm 38 at 80, and this circuit, formed by the battery 76, the wires 77 and 78, the armature-arm 55, and parts connected therewith, is intended for the purpose of heating the platinum wire 58, which is done for the purpose of burning the necessary dots and dashes of the Morse system in the tape 9 as the latter is drawn through the instrument.

The operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawings, and the following statement thereof.

The electrical impulses are received by the instru ment,being transmitted thereto by means of the key 70 and the circuit-wire connected therewith in the usual manner, and at each operation of said key'the armature 40 and armature-arm 38, with which said armature is connected, are operated, and the free end of the armature-arm is raised and lowered in the usual manner and as will be readily understood. During the entire time that the instrument is; inoperation the circuit formed by the wires 77 and 78 and parts connected therewith is closed and the platinum wire, 58 is highly-heated, and when the free end ofthe armature-arm is drawn down by the magnets 37 the said wire is pressed upon thetape 9 by the pointed end of the asbestos block or-member 53", and the necessary dots and dashes are formed in said tape by the burning thereof by means of said platinum wire.

The tape 9 is preferably composed of very thin celluloid material, and by adjusting the frame 12 transversely of the plate or support 5separatelines of perforations maybe formed IIO in said tape, as will be readily understood, and in the operation of receiving a message the pointed end of the asbestos block or member 53 and the platinum wire connected therewith move downwardly through the central slot 33 in the plate 29, and the adjustable block 23 is designed for use in connection with said plate and directly beneath said slot when a very or unusually thin tape is employed, the object of this block being to prevent the tape from being forced too far downward through the slot 33 in the plate 29.

The tape 9 may consist of an endless strip, in which event in order to repeat the message or retransmit it said tape is continuously fed through the instrument after the message has been received, and in this case or when the instrument is used as a repeater or transmitter the heating-circuit is opened, as is also the transmitting-circuit formed by the ba tery 64 and the wires and 66 and parts connected therewith, and the transmitting or re peating circuit formed bythe battery '71, the wires 72 and 73, and parts with which said Wires connect is closed, and as the tape passes through the instrument the armature-arm is operated by the rise and fall occasioned by the pointed end of the asbestos block or member 53 passing into and out of the dots and dashes previously formed in the tape by the reception of the message, it being understood that the transmitting or repeating circuit is in practice provided with a sounder by means of which the message when transmitted or repeated may be read by sound in the usual manner.

In using the instrument as a transmitter or repeater the screw 49 is adjusted so as to pull on the spring 48 and the magnets 37 are not in operation and the screw 44 is also properly adjusted with relation to the free end of the armature-arm, and in this operation of repeating ortransmitting the supplemental frame or block 20 is adjusted transversely of the plate or support 5, so that the lowerend of the ashestos block or member 53 and the platinum wire connected therewith pass through the supplemental slot 34 in the plate 29, and the downward movement of said parts is limited by the said supplemental frame or block 20, which is directly beneath said slot, as shown in Fig. 3.

[twill thus be seen that I accomplish the object of my invention by means of a device simple in construction and operation, and it will be apparent that my invention is not limited to the method of wiring the circuits herein shown and described, as anysuitable circuit or circuits may be employed, the only transmitting a message and connected with the posts 62 and 63, the wire 75 being employed in this event, as hereinbefore described. It will also be apparent that many other changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages, and I reserve the right to make all such alterations therein as fairly come within the scope of my invention.
